问题 I am new in SQL server 2017 for JSON result. I am storing JSON array in one column in my table. I am saving id's array in that table, but i want to update its relative text from other table, so please help me in this. create table #subjectList(subjectID int identity(1,1),subjectName varchar(50)) insert into #subjectList(subjectName) select 'Math' union all select 'English' union all select 'Hindi' union all select 'PC' union all select 'Physics' select * from #subjectList Create table

问题 I need to create a query that pulls only the customer_no column (because the software restrictions are as such, and I can't code it externally). But I need to be able to sort the data by create_dt (in reverse) column. The code/SQL is restricting me in using the following because in order to sort by something that data has to appear int the select statement. I can't have it appear there – is there any way around this? Select Distinct top 3500 a.customer_no From T_CUSTOMER a WITH (NOLOCK) JOIN

问题 I have the following snippet of code in my WCF web service that builds a set of where conditions according to the formatting of the values of a provided dictionary. public static Dictionary<string, string>[] VehicleSearch(Dictionary<string, string> searchParams, int maxResults) { string condition = ""; foreach (string key in searchParams.Keys) { //Split out the conditional in case multiple options have been set (i.e. SUB;OLDS;TOY) string[] parameters = searchParams[key].Split(';'); if

问题 I'm very new to SQL and T-SQL, so please forgive any mistakes in terminology or if the answer is obvious - I don't even know where to start googling for the solution to this problem. I only have SELECT permission on a T-SQL server. I have a query that pulls a bunch of information based on an event with a Start Date (DATETIME) and End Date (DATETIME). I want to have a calculated column in my query result that indicates whether the person was just involved in back-to-back events. So, something

问题 I have a situation which I think can be compared to services like CamelCamelCamel, Keepa and so on. Lets say I track the price of an article on each day for a couple of countries. So my table, lets call it Trend , would look something like this Id Created ArticleId Country Price ------------------------------------------------- 01 19/11/05 452 US 45.90 02 19/11/05 452 CA 52.99 03 19/11/05 452 MX 99.99 04 19/11/06 452 US 20.00 05 19/11/06 452 CA 25.00 06 19/11/06 452 MX 50.00 ... 97 19/11/05

问题 I have a set of data which need to result in a new row in a table. Once this row is created I need to attach metadata in separate tables related to this information. That is I need to create my [Identity] first, get the GlobalId back from the row, and then attach [Accounts] and [Metadata] to it. Inserting data and getting the Id of the inserted row is easy enough (see query below). But I'm stumped as to how I get the personnumber , firstname , and lastname inserted into this temporary table
